Be it known thatvI, BENJAMIN a citizen of theUnited States, ,residmgat Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful lmprovements in Loose- Leaf Binders; and I do hereby declare the following to be a full, clear, and exact de-' scription of the invention, such as will en-- ableothers skilled in theart to whichit appertains tomake and use thesame. a I 1 This invention relates :to binders for loose leaf records, and theprimary object of the invention is to provide a binder of this type that is of such construction that the same will serveas a support for holding the bound leaves in a position where convenient access can be'had leaves.

Another object of the invention is the provision of a binder and support of this type that will admit of the leaves being expeditiously filed or removed, as desired Other objects will appear and be better understood from that embodiment of my invention of which the following is a specification, reference being had to the accompanying drawings forming a part thereof, in which:

Figure 1 is a perspective view of a loose leaii1 record with the binder associated therewit Fig. 2 is a longitudinal sectional view taken through the loose leaf record, with the binder in supporting position and shown in vertical section,

Fig. 3 is a perspective view of the loose leaf record and binder with the top cover of. the record in open position, and

Fig. 4 is a perspective view of the binder and the record with the binder in open position to admit of either the filing of additional leaves or the detachment of those that are filed.

Referring to the drawings in detail, the letter A designates a plurality of loose leaves that are interposed between companion pieces of card-board designated B. The leaves and card-board pieces are provided, at one end, and adjacent the longitudinal edges thereof, with registering openings C.

The combined binder and support comprise a pair of U-shaped elements 1 and 2, each of which has the free ends of the sides thereof ofi'set laterally and curved, as shown at 3. The curved ends form sections BENJAMIN D. BRINK, or GRANDRAPIDS, MICHIGAN,

i of looped membersandthe terminals of the curved ends of the elements 1 are pointed,

as shown at 4, and normally received by recesses 5 in the terminals of the curved ends ofthe element 2. The width of the element 1 is less than the width of the element 2 and the points of juncture between the sides of the element 1 and the offset upper ends 3 'are flattened, as shown at 6, and liein engagement with the inner'sides of similar flattened surfaces 7 at the points of juncture between the sides and offset ends 3 of the element 2. Adjacent fiat surfaces 6 and 7 have registering openings therein and a rod- 8 lies between the flattened surfaces 6 on the sides of the element 1 and has the ends thereof loosely received bythe openings in the respective adjacent flattened surfaces 6 and 7.

A spiral spring 9 encircles the rod 8 and has one end extended around theadjacent offset portion 3 of the element 2 as shown at 10, and the other end of the spring extends around the adjacent offset end 3 of the element 1 as shown at 11. l Vhen the members 1 and 2 are moved in the direction of each other, the curved upper ends thereof will be moved in a direction away from each other, and the spring 9 will be tensioned so that upon release of the elements 1 and 2 the spring 9 will return them to normal position so that the opposed offset curved ends 3 of the elements 1 and 2 will cooperate to provide elliptical shaped loops, as shown more particularly in Fig. 2 of the drawings. When the curved upper ends 3 of the respective members 1 and 2 are separated, the curved ends can be passed through the openings in the leaves A and cover card-board pieces B, so as to bind the leaves and cover.

A hook 12 has one end loosely mounted on the lower cross bar of the U-shaped ele ment 1 and when it is desired to file a large number of leaves, the members 1 and 2 are moved toward each other so as to separate the upper ends of the respective elements 1 and 2 and the bill portion of the hook 12 is then engaged around the cross bar of the U-shaped element 2, so as to prevent the spring 9 from returning the elements I and 2 to normal position during the filing operation. The lower connecting bars of the U-shaped elements 1 and 2 cooperate to provide a supporting base for holding the elements 1 and 2 in vertical .position, as shown in the drawings, whereby the Patented Dec. 4, 1917.
